LOCK.

Application filed. May 12,

To all whom it may oonccm:

Be it known that I, AUGUSTINE DAVIS, a citizen of the United States, and a resident of Jamaica, Long Island, in the county of Queens and city and State of New York, have invented a certain new and useful Improvement in Locks, of which the following is a specification.

The invention relates to looks, and particularlyto locks such as are used in coincontrolled lockers. In these lockers the locker compartments are built in tiers with the coin locks for the compartment doors of each vertical row set in openings in the appurtenant stile member. The plates of the locks are mounted in the stile so that they can be readily taken out of the openings for replacement in event of loss of a key, and it has been customary to provide locking means for securing them in the openings, such locking means involving a vertically extending locking rod common to the vertical series of locks and a key-lock at one point in the frame for locking this rod or controlling access thereto. Considerable trouble has arisen from the use of such lockin rods, and this difficulty the present invention aims to overcome, which is accomplished by providing a directly-carried locking-in lock for each of the door locks.

In the accompanying drawings, forming a part hereof:

F 1 is a front elevation of a lock embodying the invention; and

Fig. 2 is a side elevation thereof, with portions broken away and in section, set in the opening of the frame or stile member, which is shown in vertical section.

The drawing illustrates a form of coincontrolled locker-lock in commercial use, the same comprising a vertically elongated plate 2 carrying a key-lock 3 having a bolt 4 which when projected locks the locker door (not shown). The lock is controlled by a coin deposited in the coin-entrance 5, and in the particular form illustrated the bolt 1922. Serial No. 560,287.

is shot as the result of turning the knob 6 after deposit of the coin, the key being then removable, and is subsequently retractible by operation of the key-check 7 The par ticular manner in which the operation of the lock and the removal of the key are controlled by the coin is, however, not essential, and other forms of coin-controlled locker locks may be employed.

The plate 2 is set in an" opening in the face of a stile member 8, beneath one edge of which, as the lower edge, it is caught by suitable fixed lugs 9. At another point it is locked in the opening by retractible looking means, which is here constituted by a key-lock 10 which is carried by the plate 2. The bolt 11 of this lock when retracted permits the lock structure as a whole to be tilted out of the opening, and when projected catches behind the edge of the opening or in a suitable keeper 12, so that the locker lock is securely fastened against displacement. The attendant or an authorized person is provided with a special key which enables him to unlock and lock the lock ing-in lock 10 of the several locker locks, in order to replace them when necessary, or to afford access to the locker for a patron who may have lost his key. It will be seen that each locker lock is positively locked in place by this system, and that any lock can be unlocked forremova-l without in any way affecting other'locks in the vertical row, which is an advantage over existing practice.

The locking-in lock is shown at the top of the removable lock panel, but may be disposed in other positions thereon.

What I claim as new is:

A look comprising a plate adapted to be placed in an opening and carrying a look mechanism having a bolt for locking a closure, in combination with a second key lock carried by the plate and having a bolt for locking the plate in its opening,

AUGUSTINE DAVIS.
